The little-studied problem of the effect of natural 
and forced convection on the stationary (combustion) and critical 
(ignition and extinction) high-temperature states of a carbon particle 
with account for radiative heat exchange with the cold walls of the 
processing setup is considered. The effect of molecular and convective 
heat and mass exchange of a carbon particle with a gas on the critical 
diameter of the particle de at which the particle is spontaneously 
extinguished (a jumpwise transition from combustion to oxidation) 
is analyzed.
